Election Day in Cicero and 2nd District. Polls open from 6 a.m. to 7 p.m.

Voters are headed to the polls today to pick the likely successor to disgraced former U.S. Rep. Jesse Jackson Jr. in a congressional district covering the South Side and south suburbs.

There are primaries for both political parties, but the 2nd District is so heavily Democratic that whoever emerges from the crowded Democratic field is expected to easily win the April 9 special general election. Polls are open from 6 a.m. to 7 p.m.

Today's voting follows weeks of candidate forums, an accelerated campaign schedule and a flurry of TV ads from the mayor of New York. While the top-tier candidates among the 14 Democrats vying for the primary nomination are known — former state Rep. Robin Kelly, former U.S. Rep. Debbie Halvorson and Chicago 9th Ward Ald. Anthony Beale — there also are some big unknowns. Voter turnout, already anticipated to be very low, could be exacerbated by nasty weather.

Kelly voted early. Beale and Halvorson planned to vote today. All three candidates have a slew of campaign stops scheduled before gearing up for evening parties where they'll watch the results come in.

The results of early voting held between Feb. 11 and Saturday demonstrated a lack of interest in the contest, despite its ramifications in deciding who will represent voters and their disparate interests in the vast district.

A majority of the district's Democratic voters live in suburban Cook County, with an additional one-third from the South Side. The district also includes parts of eastern Will County and all of Kankakee County, and together the two regions make up slightly less than 10 percent of the Democratic vote.

In suburban Cook, 4,459 early votes were cast, with 98 percent of those voters taking Democratic ballots. Of the 11 suburban early voting locations, Matteson Village Hall, in Kelly's hometown, had the most with 1,601 voters.

In Chicago, 98 percent of the 2,768 early voters cast Democratic ballots. Only 63 early votes were cast for Republicans.

In Will, 246 voters cast early ballots, all but 40 of them Democratic votes. Kankakee County officials reported 699 early ballots, with 533 voting Democrat and 166 Republican.

"I just think if it was a regular race, then they'd look a little bit different," Kelly said of the low early voting totals. "I also think because (the special primary) came so close to the November election that there's some (voter) fatigue."

But in a large field of candidates and questionable turnout, a nomination for Congress could be decided by mere hundreds of votes. Even as forecasters sounded warnings of a Tuesday smorgasbord of wintry weather, candidates sought to energize core supporters to help get out the vote.

In an email to supporters, Kelly's campaign pleaded for volunteers to help get voters to the polls and asked for money for its get-out-the-vote field operation.

Halvorson acknowledged the early voting numbers were "paltry" and that voter turnout would be a "huge" factor Tuesday. Halvorson said she believed turnout could be driven by the district's history of scandals — including last week's guilty plea by Jackson on federal charges of illegally converting about $750,000 in campaign cash to personal use.

"I think this race has gotten so much attention and people are so angry about what the 2nd Congressional District has had to deal with over the years that they're going to take a special interest to make sure they are going to vote for someone who is completely different than what they've seen," said Halvorson, of Crete.

Halvorson also has been the target of the most extensive advertising in the contest, more than $2.2 million worth of TV and mail attacks by New York Mayor Michael Bloomberg's super political action committee, centered on her past National Rifle Association support. Bloomberg's Independence USA PAC is backing Kelly.

Beale said the low number of early ballots puts all the more importance on Election Day field efforts. He said that well-established organizations in the six city wards in the district could serve as an advantage for his campaign.

"It's just slow across the board, and that just goes to show it is going to be a very low turnout," Beale said of the early votes. "We're just making sure we're targeting our core, solid voters, and we're going to get them out to the polls and be victorious Tuesday night."
